New Mercedes-AMG GT Roadster And GT C Roadster

Mercedes-AMG reveals the core strengths of its new, open top, sports cars.

AMG GT Coupé range gains soft-top siblings

The Mercedes-AMG GT Roadster and GT C Roadster are new, open top, versions of the brand's most prestigious sports car; the GT. Siblings include the: GT Coupé (462hp), GT S Coupé (510hp) and the GT R Coupé which is the hard-core, track-focussed, version (585hp). 

Engines, 0-62mph times and top speeds

The GT Roadster is the slightly tamer of the new variants. Power comes via a 4.0-litre, V8, twin-turbocharged, petrol engine that produces 476hp at 6,000rpm and 630Nm of torque between 1,700 and 5,000rpm. Expect 0-62mph in 4.0 seconds plus a top speed of 187mph.

AMG said: “The 8-cylinder engine thrills with its immediate response, linear finely controllable power delivery, and powerful acceleration in all rpm ranges.” Furthermore, the turbochargers sit in the centre of the V – between the 2 banks of 4 pistons, in other words - to optimise their responses and minimise exhaust emissions.

The Mercedes-AMG GT C Roadster builds on its bedfellows strengths so is even more powerful. Its 4.0-litre, V8, twin-turbocharged, petrol engine produces 557hp between 5,750 and 6,750 rpm. This power plant also generates 680Nm of torque between 1,900 and 5,750rpm. Expect 0-62mph in 3.7 seconds plus a top speed of 196mph.


The GT Roadster and GT C Roadster have 7-speed, dual clutch, automatic transmission. The AMG Dynamic Select Controller enables motorists to pick: Comfort, Sport, Sport Plus and Individual Modes to tweak its responses based on personal preference. Choose sportier, higher-rev, changes when fun is top of the list, perhaps.

The Mercedes-AMG GT C Roadster incorporates Race Mode too. As the name suggests, it optimises the response of the automatic transmission to suit a race track. “Very fast shift speeds and highly emotive engine sound are included”, the manufacture claimed.


The GT C Roadster has a performance exhaust and its flaps open/close to change its tone based on AMG Drive Select Settings. Sport Plus produces a more “emotive” sound, for example, whereas Comfort produces a low-frequency pulse most typical of a V8 engine.


The GT Roadster has sports suspension that provides “optimum, highly precise, road feedback right up to the very high cornering limits”, the manufacturer said. The GT C Roadster, in contrast, adds AMG Ride Control that tweaks the response of the dampers based on the prevailing “handling situation, speed, and road conditions”.

Other strengths

These Roadsters have other strengths too. Highlights include the:

  • electric, fabric, roof that operates in about 11 seconds at up to 31mph and is available with a black, red or beige finish;
  • muscular styling that incorporates a long bonnet, wide rear and striking alloy wheels;
  • choice of 11 exterior and 10 interior colours.
